Adjusting the fan speed of the USG6000

To adjust the fan speed, run the test fan-speed fan-id fan-speed command in the diagnose view. This command involves two parameters.
fan-id specifies the fan ID, which can be 0, 1, and 2. 0 and 1 specify the ID of the corresponding fan, and 2 indicates all fans.
fan-speed specifies the fan speed, which is an integer ranging from 0 to 4 or 0 to 7, according to the model. A larger value indicates a faster fan speed. The maximum value indicates that the fan runs at the full speed.
